August 14: I had my second prenatal appointment this afternoon, and I got to hear the wee one’s heart beat. Click hear, and you can hear it too. Baby’s hearts beat is about 150 times per minute. I’m fourteen weeks into the pregnancy, and so far, everything is going well:)
Here’s the week 14 update from Babycenter.com
Welcome to your second trimester! This is a big milestone because it marks the end of a critical development period.
All the basic structures of your baby’s body are formed now. Head to bottom, your baby is just 3 1/2 inches long — about the length of a lemon — and weighs about 1 1/2 ounces. She’s starting to develop an ultrafine, downy covering of hair all over her body called lanugo.
Thanks to brain impulses, her little facial muscles are getting a
workout as she squints, frowns, and grimaces. She can grasp now, too, and she may be able to suck her thumb.
